The Rockets missed eight straight shots from the field to lose control of their comeback. Harden fumbled the ball with a minute a left and Young was there to pick it up and fire to Holiday, who took one look over his shoulder and put in the easy layup for a 104-94 lead.
Holiday sank two free throws to hit the 30-point mark, falling three points shy of matching his career high set in November against Phoenix. He made 11 of 22 shots, sank all seven attempts from the free-throw line and had nine assists (with six turnovers).
"We needed it," Holiday said. "Going into this home stretch, getting the first one is huge. Home court is big. It's crucial. On the road, we didn't do what we wanted to do. We've got to come here and try and win at home."
Houston's cold stretch was uncharacteristic of a team that was second in the NBA in scoring (105.60 points) behind Oklahoma City. The Rockets only shot 30 percent from 3-point range (8 of 32) and had no answer to stop Holiday en route to their third straight loss.
"Teams are getting out to some good leads on us and we try and fight back," Harden said. "We get it back to a two- or three-point game and then run out of energy."
Collins has noted this team's missing energy to open second halves over the last month. Against Houston, they started slow, trailing by 11 before ending the quarter on a 20-6 run. Turner scored 12 points in the second quarter to help the Sixers take a 58-50 lead into halftime.
The Sixers held on to avoid a season-high losing streak and win for only the fourth time in 17 games.
